Description

Technical Field

[0001] The utility model relates to the technical field of wire harness processing, in particular to a circular cutting device for processing electrical wire harnesses. Background Art

[0002] In many fields, such as electrical appliance manufacturing, wire harnesses need to connect to various electrical components (such as plugs, sockets, and terminal blocks). By removing the insulation layer by circumferentially cutting the ends of the wire harnesses, the internal wires can be directly exposed, providing excellent conditions for connection methods such as welding, crimping, or plugging, thereby ensuring stable and reliable connections.

[0003] In Chinese Patent 202021492918.X, the utility model discloses a circular cutting device for processing electrical wiring harnesses, including a cutting workbench with a wiring harness conveying unit disposed above the cutting workbench. The circular cutting device for processing electrical wiring harnesses has two sets of telescopic tool holders disposed inside the circular cutting chamber for telescopic adjustment, and the circular cutting blades are mounted at the ends of the telescopic tool holders. By adjusting the telescopic tool holders, the spacing between the two sets of blades can be controlled. During cutting, the spacing between the blades needs to be greater than the cortex thickness of the wiring harness production specifications. This can avoid damaging the internal structure of the wiring harness due to inaccurate cutting feed rate. At the same time, the gap needs to be controlled between 0.2mm and 0.4mm. This can avoid excessive thickness after cutting, which prevents the cortex from being unable to detach from the wiring harness. After the circular cutting work is completed, the de-line splint on the fixed shaft clamps one end of the wiring harness, while the de-line splint on the movable shaft clamps one end of the cut cortex. The movable shaft then moves outward, and the cut cortex is separated from the wiring harness body by tension.

[0004] The existing circular cutting device for processing electrical wiring harnesses exists after completing the circular cutting of the cortex at the end of the wiring harness. It clamps the two ends of the wiring harness and pulls hard to remove the cut cortex ring from the wiring harness. The insulating cortex and the internal wire are wrapped tightly, and it requires a large force to remove it only by pulling. The wires in the wiring harness are usually composed of multiple strands of thin copper wire or aluminum wire. Pulling hard will cause the wires to be subjected to excessive tension, which may cause some of the thin wires to break, which may affect the electrical performance of the wiring harness, and may further damage the wires, and even cause subsequent circuit problems.
